User OneSignature has shared on the Bitcointalk forum a message encrypted with a private key corresponding to a public address from January 2009. This user remains anonymous and the address is empty, with no funds. The curious thing about this case is that this address is one of the first Bitcoin addresses. It is an address of one of the first miners and, on January 19, 2009, 10 days after the birth of Bitcoin, he received 50 bitcoin (BTC) as a reward for his activity.
The appearance of this direction of the times in which Satoshi Nakamoto was active has caused quite a stir and many users even began to speculate that the address belonged to the creator of Bitcoin and the first miners of the network, with some even doubting the credibility of the message encrypted by OneSignature.
In addition, this address would also be related to Hal Finney, the first user to receive a Bitcoin transaction who passed away in 2014. After receiving the funds in 2009 this address remained dormant until all the funds, along with another 2011 BTC, were transferred to a single address in 2000.
When sending Bitcoin funds, the protocol allows funds from different addresses to be sent to a single address, as long as the private keys are held. Also, in the data analyzed, it can be seen that some of the transaction entries match one of the addresses identified as belonging to Finney and another of the user. OneSignature, which means that the user may have access to the rest of the private keys on the list and perhaps also to Finney's bitcoin.
